SAW-FILER.

SPECIFICATIONforming part of Letters Patent No. 753,575, dated March 1,1904.

Application filed July 2, 1903. Serial No. 164,094. (No model.)

Be it known that I, JOHN M. HOLLADAY, a citizen of the United States,and a resident of Holladay, in thecounty of Spottsylvania and State ofVirginia, have invented a Saw-A Filer, of which the following is aspecification.

This invention relates 'to improvements in saw-filers; and the mainobjects in view are to produce a simple and economically-constructeddevice adapted to be readily and securely clamped on circular saws inproper re- -lation with the teeth thereof, which will accurately andpositively guide and regulate the le in its operation of vsharpeningsaid teeth, which when once adjusted to the pitch of the teeth may besubsequently moved to and throughout the succession of teeth, and whichis equally adapted for the ling of the chisel or both right and lefthand briar teeth;

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be particularly pointed out ,in theclaims. A

Referring to the drawings, Figure 1 is al side elevation, and Fig. 2 anedge elevation, of the preferred form of saw-filer, the former ligureshowing the saw to be operated upon in dotted lines. Fig. 3 is a sideelevation of a modified form, and Fig. 4L a top plan view of the same.Fig. 5 is an elevation similar to Fig. 1, illustrating a modification;and Fig. 6 is a plan thereof. Figs. 7, 8, and 9 are de-0 tailshereinafter referred to in connection with Fig. 5. Fig. lO-is a planview of- Fig. 11, and Fig. 11 is an elevation of a still fur- .thermodification hereinafter referred to.

Fig. 12 is an edge elevation of Fig. 1.1,. Fig. 13 is a detailhereinafter-referred to. y

Similar numerals of reference indicate similar parts in all the guresofthedrawings.

My device, which I term a saw-filer, comprises in each instanceillustrated a pair of clamping-plates 1 and 2, the two being perforatedin transverse alinement. The two plates are designed to clamp upon acircular saw, and in order that the clamping may be readily accomplishedas the device is moved from point to point of the saw to operatesuccessively upon its teeth I preferably employ in each instance aconnecting-bolt 3, which passes through the two plates 1 and 2 and whichat one end may be provided with an ordinary thumb-nut, or, as shown,with a ratchet-nut 4:, the teeth of which are caused to engage andinterlock with a toothed Washer '5. Upon the bolt 3 between theclampingplates 1 and 2 I may locate an expansive coiled spring 6 tonormally spread or separate the two clamping-plates as far as the boltand nut will permit.

i Referring more particularly to Figs. 1 and 2, it will be seen that Iextend the upper rear corner of the clamping-plate 2 above its companion1, thus forming a short ear 7, and upon a transverse pintle 8, passedtherethrough, I loosely mount the rear end of an arm 9, of irregularshape, and which may have formed in its under side, near its front andfree end, one or aplurality of notches-in this instance two-anddesignated as front and rear notches 10 and l1, respectively. In thisinstance, asin all other forms shown, the clamping-plate 2 hasadjustably mounted thereon, by means of a bolt 12 and set-nut 13,V a.rear gage-arm 14.

Yieldingly mounted on a bolt or stud 15, extending from the face of theclamping-plate 2, is an upwardly-disposed vibratory arm 16, which maypass loosely through a keeper 22 and terminate at its upper end in anvarch 17, bridging over the upper ends of the two clamping-plates.Horizontal and parallel terminals 18 may extend forwardly from the arch,and rising from each may be any suitable design of file guide. I prefer,however, opposite pairsof pins 1-9, each carrying a loose sleeve orroller 20. These pins and rollers may be arranged as shown in Figs. 1and 2 or as in Fig. i-that is, with two or four pins and rollerstheiirst instance adapting the device for guiding and gaging a file whileoperating on a saw having chisel teeth only and in the second instanceadapting the device for guiding and gaging a iile while operating on asaw having either right and left briar teeth or both briar and chiselteeth, all as hereinafter apparent.

A flat or other form of spring 21 may be let into a post formed on theface of the clamp- IOO ing-plate 2 and at its free end bear against thearm 16, which for convenience I will term the carrier-arm in that itcarries the {ile-guides. By this means the carrier-arm is yieldinglypressed forward, being limited and guided in its movement by the keeper22, in one end of which may be located a set-screw or stop 23, thelatter limiting the rearward movement of the arm.

From the front upper end of the clampingplate 2 rises a locking-standard24, the same having an overhanging shoulder 25, above which the standardis rounded off or beveled. This shoulder 25 overhangs the path of thearm 9, whereby the arm when depressed is sprung into and engaged by theshoulder and temporarily locked in a depressed position.

This completes the description of my preferred form of saw-filer, andthe operation of the same may be briefly outlined as follows: The nut 4having been loosened, the clampingplates spring' apart and are setastraddle of the saw. (See dotted lines, Fig. 1.) When this is done, thenotch 10, if it is a briar tooth, or the rear notch 11, if it is achisel tooth, that is to be filed, will engage with said tooth. Thedevice as a whole is then given the desired inclination, and when soadjusted the tail of the arm 14 is lowered until it rests on the end ofthe next succeeding rear tooth,

after which the nut 13 is tightened. The

arm 14 may be of other shape than that shown and may rest on any part ofthe saw and not necessarily the point of the tooth. Having thus adjustedthe parts the clamping-jaws are now closed tightly and by means of thenut4 and bolt 3 are caused to tightly embrace the saw. The frontgage-arm 9 is now thrown to the rear and out of engagement with thetooth to be filed. (See Fig. l.) If the tooth be of the chisel style,the lile is run back and forth across the front faces of the two rearrollers or sleeves 20, the latter being pressed backward, and thusyielding to the pressure of the file against the tendency of the spring21. rIhis backward movement of the guides will of course be limited bythe set-screw 23, against which the carrier-arm 16 abuts eventually.Having led this tooth, which it will be seen can be accomplished byunskilled labor, the arm 9 is again thrown into engagement with notch 25of the standard 24, the

' nut 4 loosened, the plates l and 2 separated by the spring 6, and thedevice advanced to the next tooth. When thus advanced, the rear notch 11of the arm 9 is engaged with the tooth to be filed, the device lowereduntil the rear gage 14 rests on the tooth last filed, and

' the nut 4 again tightened to clamp the device in position. The arm 9is then released and swung back out of the way and the tooth filed asbefore. In case it is a briar tooth that is to be filed the operation isthe same, except that the front notch 10 is engaged over the In Figs. 3and 4 I have shown a slightly- 4 modified construction. In this instancethe upper end of clamping-plate 2 is linished on? flat on its upper endand at its rear side provvided with a depending lug 26, having atransverse perforation 27. A horizontal plate 28 is mountedon theclamping-plate 2 and is adjustably swiveled thereon by means of a bolt29, having a` clamping-nut on its lower end. The plate 28 at its rearend extends beyond the plate 2 and is formed with a depending flange 30,having a central hole 31 and at either side thereof a hole 32. (See Fig.4.) A U-shaped spring-catch 33 has one terminal let into the rear edgeof the clamping-plate 2 and its other terminal laterally disposed, as at34,

passed through the perforation 27 and may be temporarily` engaged witheither of the holes 31 or 32. By loosening the nut on the bolt 29 theplate 28 may be set at either angle or parallel to plate 2 and so heldby spring-4 catch 33 and subsequently tightly secured by the nut on bolt29. Rising from the plate 28 is a standard or ear 35, and pivotedtherein `by the pintle 8 is the arm 9, which in this instance may beprovided with a single notch 36. From the front end of the plate 28there rises the heretofore-described notched locking-standard 24. Therear edge of the standard 35 and standard 24 are slotted, as at 37, andnormally mounted within the same is a guide-frame-carrying plate 38,from the forward end of which there extends a slightlydepressedyoke-shaped guide 39, from which in this instance rises a pair oftransverselyopposite pins 19, each having a loose sleeve 20. Acurvedspring 40, interposed between the standard 35 and plate 38, serves toyieldingly force the latter forward. It will be observed that in thisinstance the main point of difference is that the carrier 38 is slidablymounted instead of pivotally mounted, as here'- inbefore described.

Referring more particularly to Figs. 5, 6, and 8, it will be noted thatboth the carrier 41 and front gage-lever 9 are mounted on the pintle 8of the standard 7. The device herein illustrated is intended for thatclass of lighter circular saws employing the usual form of saw-teeth,and the carrier 41 is preferably mounted, as shown, and divided at itsfront to form the yoke 43, at the extremities of which are supported thedownwardly-inclined IOO IIO

guides 20. This carrier is further'provided with an opening 42, upwardlythrough which' projects the locking-standard 24, having the"y the lug 71, the latter rising from a plate 47,

widened at its rear end and having a segmental slot 48, through whichprojects from a similar extension 49, formed on the clamping-plate 2, abolt 50, carrying at its upper end a winged nut 51. (See Figs. 7 and 9.)The carrier in this instance is swiveled on the standard 24, which ismade cylindrical, (see Figs. and 6,) and hence maybe given any necessaryangle and secured by the nut 51 in the adjusted position, whereby bevelsmay be iled, if necessary.

Referring to Figs. 10 to 13, it will be seen that the main differenceresides in the means of attaching the guides on the carrier andarranging for their adjustment. In this instance one of the guides 2O isfXedly mounted on one arm of the carrier-frame 17a, while the companionguide is adjustably mounted on the opposite arm thereof. This matter ofadjustment may differ, and I have illustrated in the figures referred totwo convenient ways. In Fig. 13 I show the carrier-arm slottedlongitudinally, as at 52, the post 19 mounted in the slot and held by anut 53. Another convenient way is illustrated in Figs 11 and 12, whereinone of the carrierarms is formed ,with a rib 54, engaged by an opposingrib or flange 55, formed at the inner edge of an inverted-L-shaped plate56. The vertical liange of the latter is slotted, as at 57, andprojecting outward through the slot from a block 58, inclosed by theplate 56, is threaded stem 59, upon which is mounted a milled nut 60.
